Loose Organic Tea in Santa Clara co. / Sunnyvale area?
I remembered another tea merchant, Mountain View Tea Village in downtown Mountain View.
I've been there once or twice, and the lady who helped me (perhaps one of the owners?) was friendly and well-versed in teas. I had gotten some fantastic pu-erh and pearl orchid. Most of the teas were from China and Taiwan, iirc; not sure how many organics they carry.
There's Tea Time in downtown Palo Alto. I haven't been there for 1-2 years, but in the past they were quite knowledgeable tea merchants.
One of the big reasons I rarely go there these days is because of Upton Tea Imports, which sells bulk loose leaf tea online --with several organic choices as well.
However, I'm still interested to hear about other bay area tea merchants, especially any who are in the south bay.
